Popis: Research focuses on the perceptions of engineers towards highway projects contract types' (CTs) performance and their respective selection criteria (SC). A questionnaire survey evaluated the CTs against the selected criteria. The SPSS database's sample consisted of 91 engineers from Greece and abroad. Factor analysis identified groups of selection criteria representing the performance of each CT and reflecting the engineers' perceptions. Patterns of changes in engineers' assessment of the contract types' performance were noted and justified. Apart from the total sample, analysis considered participants' subgroups, such as Greek and foreign engineers, and experienced engineers in the private and public sector. Nationality and experience of participants influence the factors' content. Moreover, a number of criteria tend to cluster together irrespective of CT and engineers' profile. These pairs of criteria include all uncertainties' criteria, Scope and Process Uncertainty, Contractual Difficulties and Claims, and finally Value for Money and Criticality of Schedule.
